The southwestern interior region of BC is semi-arid and its relatively infertile soils lack nutrients and organic matter. Adding biosolids to rangeland and hayfields helps build healthy, productive soils by providing organic matter and nutrients, improving soil water retention, increasing vegetation growth and decreasing soil erosion.
Studies conducted by Agriculture Canada on these lands have shown that biosolids use improved soil health and increased the amount and quality of grasses available as forage for livestock. At OK Ranch north of Clinton, research conducted by the Ministry of Forests shows that grasslands in poor condition have been restored to a healthy, productive state with only one application of Nutrifor™.
